Re: [PATCH v2] drm: fix error found in some cases after the patch d1af5cd86997

[Claudio Suarez <cssk@net-c.es>]

The patch d1af5cd86997 ("drm: get rid of DRM_DEBUG_* log
calls in drm core, files drm_a*.c") fails when the drm_device
cannot be found in the parameter plane_state->crtc.
Fix it using plane_state->plane.

Reported-by: kernel test robot <oliver.sang@intel.com>
Fixes: d1af5cd86997 ("drm: get rid of DRM_DEBUG_* log calls in drm core, files drm_a*.c")
